Parents choosing individual snack packs
An inner bag has a stated weight, making it easier to check the portion and its nutrition information. A baked label alone does not tell you the fat, salt or allergen details for every flavour.
Who is this choice for?
Families comparing fat and salt separately
A reduced-fat claim answers only part of the question. Compare fat per 100g on like-for-like labels, then check salt for the particular crisp and portion you are considering.
Parents checking allergies or dietary preferences
Check the ingredients and precautionary allergen statement for each current flavour. Vegetarian, vegan and gluten-free descriptions apply to the labelled product, not automatically to every crisp from the same brand.
What should you compare?
For a reduced-fat half-term crisp snack, compare fat on the same weight basis before checking salt, the inner-bag size and the exact flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Fat comparison | Look for a quantified claim with a named comparator, then compare fat per 100g. Walkers says Oven Baked Sea Salt has 50% less fat than regular potato crisps and lists 13g fat per 100g. | I want to know what a lower-fat claim is being compared with, rather than choosing by a lighter-sounding name. |
| Salt | Read salt per 100g and per bag on the exact flavour. Walkers lists 0.85g per 100g and 0.19g per 22g bag for Oven Baked Sea Salt; those figures should not be applied to other flavours. | Reducing fat matters to me, but I also want to compare the salt in the bag being served. |
| Portion size | Check the weight of each inner bag, not just the number of bags in a multipack. Use per-100g figures to compare products and per-bag figures to understand that portion. | For a half-term snack, I would rather know the amount in one bag than treat a multipack or sharing bag as one serving. |
| Snack choice | Consider whether crisps are being chosen for an occasional savoury packaged snack or as a routine snack. NHS Healthier Families recommends fruit and vegetables for children’s snacks and suggests plain popcorn, plain rice cakes or raisins as swaps for crisps. | Sometimes crisps are what my child wants; on other days, a different snack would meet the need. |
| Ingredients and allergens | Read the ingredient list and any may-contain statement on each current flavour. Do not extend one flavour’s vegetarian or other dietary label to the whole range. | If an allergy or dietary preference affects the choice, I need to check the particular pack before serving it. |
Common buying mistakes
-
Assuming “baked” answers every nutrition question
A baking description does not tell you the salt content or portion size. Walkers lists 13g fat and 0.85g salt per 100g for Oven Baked Sea Salt, so both figures matter when comparing it with another product.
Check the quantified fat claim, then read fat and salt per 100g and per inner bag on the flavour you are buying.
-
Comparing bags of different sizes as though they were equal
A 22g baked-crisp bag and a 30g lentil-crisp serving contain different amounts of food. Their per-bag figures alone are not a like-for-like product comparison.
Compare labels per 100g first, then use each bag’s weight and per-serving figures to assess the portion.
-
Making reduced-fat crisps the default snack
A reduced-fat claim compares fat with another product; it does not make crisps interchangeable with fruit or vegetables. NHS Healthier Families recommends fruit and vegetables for children’s snacks.
Choose crisps when an occasional packaged savoury snack is wanted, and consider the NHS-suggested alternatives for other snack occasions.
-
Applying school-food rules to snacks eaten at home
The Requirements for School Food Regulations 2014 concern food provided to pupils in specified schools and pupil referral units in England. That is a different setting from a parent buying a half-term snack for home.
If food is being provided at school, check the school-food requirements that apply to that setting rather than assuming a retail reduced-fat claim establishes menu suitability.
Brand and product-line references
These labelled examples show why the product and flavour matter more than the brand name when comparing reduced-fat crisps with other savoury snacks.
Walkers
Walkers Oven Baked Sea Salt is a potato-crisp-style option with a stated fat comparison.
- Walkers says this product has 50% less fat than regular potato crisps; its label lists 2.8g fat and 0.19g salt per 22g bag.
- The claim and figures describe this product, not every Walkers flavour. Check the current pack for allergens.
Tyrrells
Tyrrells lentil crisps are an alternative for families willing to choose a different base ingredient from potato.
- Tyrrells says its cited lentil flavours have 30% less fat than standard potato crisps on average.
- The cited 30g servings list 0.60g to 0.63g salt; compare the exact flavour and do not treat lentil crisps as potato crisps.
KETTLE Chips
Lightly Salted is a conventional potato-crisp reference when comparing labels.
- The product information lists 0.7g salt per 100g and labels this flavour suitable for vegans and vegetarians.
- It also lists 29.5g fat per 100g; “lightly salted” is not a reduced-fat claim.
Seabrook
Sea Salted is a crinkle-cut potato-crisp example with nutrition stated both per bag and per 100g.
- Its label lists 9.7g fat and 0.4g salt per 31.8g bag and marks the product gluten-free and suitable for vegans and vegetarians.
- At 30.4g fat per 100g, this cited flavour is not presented as a reduced-fat option.
Pipers
Anglesey Sea Salt is another conventional potato-crisp label to compare on a per-100g basis.
- Pipers lists this flavour as gluten-free and suitable for vegans and vegetarians.
- Its label lists 30.7g fat and 0.94g salt per 100g, so it is not the reduced-fat route described here.
REAL Hand Cooked Crisps
Sea Salt is a conventional potato-crisp example rather than a stated reduced-fat choice.
- The listed ingredients are potatoes, vegetable oils and sea salt; this product is labelled suitable for vegans and vegetarians.
- Its label lists 30.0g fat and 1.3g salt per 100g.
Joybuy crisp multipacks
These individual-bag multipacks offer baked or popped-style crisps for the occasional half-term snack. Compare each flavour’s current label rather than assuming the Sea Salt figures above apply to the other packs.

Walkers Oven Baked Variety Pack, 6 x 22g
The 22g inner bags give you a stated portion for an occasional crisp snack. As this pack contains several flavours, check each one’s fat, salt, ingredients and allergen statement rather than applying a single flavour’s figures to the whole pack.
No image available
Walkers Oven Baked Cheese & Onion, 6 x 22g
This multipack has six 22g bags of Cheese & Onion crisps. Check this flavour’s own fat and salt values and its ingredient and allergen information, particularly if the snack must meet a dietary requirement.
No image available
PopChips Sour Cream & Onion, 5 x 17g
The five 17g bags offer a smaller stated inner-pack weight than the two 22g Walkers multipacks shown here. Compare fat and salt per 100g before comparing per-bag values, and check the current pack for ingredients and allergens.
Questions about half-term crisp snacks
Does “reduced fat” make crisps an everyday snack for children?
No. A quantified claim helps you compare crisps when a packaged savoury snack is wanted, but it says nothing by itself about salt or the broader snack choice. NHS Healthier Families recommends fruit and vegetables for children’s snacks and advises aiming for no more than two packaged snacks a day.
Should I compare fat per bag or per 100g?
Use fat per 100g to compare products with different bag sizes, then read the per-bag values for the portion you plan to serve. Walkers lists 2.8g fat and 0.19g salt per 22g bag for Oven Baked Sea Salt; check other flavours separately.
Can a plain flavour or brand name tell me whether a crisp suits an allergy?
No. Read the ingredients and precautionary allergen statement on the exact current pack. Do not assume that a plain-sounding flavour, or a dietary label on another product from the brand, settles the question.
Do school-food rules determine what crisps I can buy for home during half term?
The Requirements for School Food Regulations 2014 address food provided to pupils in specified schools and pupil referral units in England, not snacks a parent buys to eat at home. If you are choosing food to provide at school, check the requirements applicable to that setting rather than relying on a retail reduced-fat claim.
Are lentil crisps a direct substitute for reduced-fat potato crisps?
They are an option if a different base ingredient and flavour are acceptable, but they are not potato crisps. Tyrrells says its cited lentil flavours have 30% less fat than standard potato crisps on average; their listed 30g servings contain 0.60g to 0.63g salt, so compare the exact variant before choosing.
